I just bought a 2015 R/T brand new and purchased the lifetime maximum care warranty as I expect to keep the car for 5 to 10 years and drive about 40k-50k miles per year. Does anybody else have experience with this plan who drives the kind of high mileage that I do? Any issues to look out for? I plan on doing very few mods so as not to possibly void the warranty, other than may be speakers. Any comments would be appreciated.
